示例1: saveWithChecksums
// buildFile saves a data file from the tar archive to disk,
// then returns a struct with data we'll need to construct the
// GenericFile object in Fedora later.
func (reader *Reader) saveWithChecksums(gf *models.GenericFile) {
// Set up a MultiWriter to stream data ONCE to file,
// md5 and sha256. We don't want to process the stream
// three separate times.
err := os.MkdirAll(filepath.Dir(gf.IngestLocalPath), 0755)
if err != nil {
gf.IngestErrorMessage = err.Error()
return
}
